[section Overview]
The header <boost/core/make_span.hpp> provides function templates `make_span`
to conveniently create `span` objects. They are useful before C++17 where Class
Template Argument Deduction (CTAD) is not available.

[section Reference]
```
namespace boost {
template<class I>
constexpr span<I>
make_span(I* d, std::size_t n) noexcept;
template<class I>
constexpr span<I>
make_span(I* b, I* e) noexcept;
template<class T, std::size_t N>
constexpr span<T, N>
make_span(T(&a)[N]) noexcept;
template<class T, std::size_t N>
constexpr span<T, N>
make_span(std::array<T, N>& a) noexcept;
template<class T, std::size_t N>
constexpr span<const T, N>
make_span(const std::array<T, N>& a) noexcept;
template<class R>
span<remove_pointer_t<iterator_t<R> > >
make_span(R&& r);
} /* boost */
```
